How to Check Because this operation can be a little difficult, you may choose to have this done at your GM dealer Service Department. Wait at least 30 minutes before checking the transmission fluid level if you have been driving: When outside temperatures are above 90°F (320C). At high speed for quite a while. In heavy traffic -- especially in hot weather. While pulling a trailer. If you do it yourself, be sureto follow all the instructions here, or you could get a false reading on the dipstick. NOTICE: Too much or too little fluid can damage your transmission. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Be sure to get an accurate reading you check your if transmission fluid. To get the right reading, the fluid should be at normal operating temperature, which is 180°F to 200°F (82°C to 93°C).
